This Radical RC 1905 Wright Flyer was built by Steve Cushing
(Vancouver, Washington; email: swcushing1@gmail.com). Powered by
t win 2830 1,000 Kv counter-rotating pusher motors, the Wright Flyer
uses a single 3S 3,300 mAh LiPo battery. The 68-inch foam wings were
formed over the ribs using a heat gun. The flying machine has a clever
wing-warp setup with dual rudders and canards.

Steve also added nylon bottoms to the skids for paved runway
takeoffs. He uses a dolly steered by a separate servo and receiver that
is bound to the rudder control for grass takeoffs.

Steve wrote, “I can’t say it’s hard to fly with the wing-warping,
canard, and pusher motors … just different. Landings are a little tricky
with no suspension, and it can be a handful in a breeze over 10 knots,”
he added, “but without a doubt, [it’s] my most favorite RC airplane!”

The Brigadier is powered by a Cox .049 Silver Stunter engine with a
Kavan Tank Extender. The radio system is a Spektrum DX6i with an
AR400 receiver. Darren uses two Hitec HS-82MG servos.

The Brigadier is covered in Hangar 9 UltraCote ParkLite Cub
Yellow and Orange. Darren wrote that the bright colors should make
the airplane easy to see if he catches a thermal.

Boeing 777x

Mahesh Chengalva (Seattle, Washington; email: drchengalva@
hotmail.com) is a Boeing engineer who works on the full-scale
Boeing 777x. The full-scale airplane was the inspiration for his
model. “I have two teenage daughters and a 10-year-old son,” he
wrote, “and thought it would be a great opportunity to teach them
about engineering by having them help me build this aircraft.”
With a 10-foot wingspan and 1,200-square-inch wing area, the

777x has folding wingtips that are locked in flight position. Weighing
slightly more than 8 pounds, the airplane is powered by two ducted-fan engines. Mahesh extensively tested the aircraft’s structural and
aerodynamic performance.

Shown in the photo (L-R) are Anita, Anisha, Mahesh, and
Dev. All three youngsters were involved in all aspects of design,
manufacturing, testing, and flying. A video of the first flight can be

P- 40 Warhawk

Gregg Ruppel’s (Ellisville, Missouri; email: ruppelgl@slu.

edu) Fun-Scale P- 40 Warhawk was built from a Dynaflite kit
approximately 20 years ago.

He wrote: “I dusted it off and reconditioned the O.S. . 40 four-stroke, which had sat idle for a long time. It handles well in the air
and the three-blade prop gives it a touch of scale.”
Gregg also used a carved balsa drop tank—a nice addition
without adding much to the overall weight.
